pdfSetPrintForceGDI

Force the print operation to go through GDI.

void pdfSetPrintForceGDI(PDFViewerHandle viewer, BOOL gdi)

If this function is called with gdi = true, all printing
will go through Windows GDI, even for PostScript printers.
If gdi = false (the default value), XpdfViewer will
generate its own PostScript code for PostScript printers and use GDI
for other printers.
